Txheeb xyuas qhov kev siv thawj zaug thiab tsim cov kev xav tau ntawm kev ua tau zoo
Daim ntawv thov sib txawv muab qhov xav tau sib txawv ntawm cov ntoo; qhia meej txog qhov npaj siv ua ntej kom txo qis koj qhov kev xaiv:
Kov rau hnyav-cov haujlwm ua liaj ua teb lossis cov cuab yeej ua haujlwm ua haujlwm: Ua ntej ntoo nrog lub zog compressive sib npaug rau cov qoob loo ntau dua lossis sib npaug ntawm 60 MPa thiab qis qis qis (xws li Dub Locust lossis Mongolian Oak). Cov ntaub ntawv no tiv taus qhov cuam tshuam rov qab thiab tiv thaiv warping los yog tawg thaum lub sij hawm ntev sab nraum zoov, muab lub neej kev pab ntau tshaj yim xyoo.
Kov riam los yog cov cuab yeej siv tes: Sib npaug hardness thiab toughness, zam cov ntaub ntawv uas nkig dhau lawm (nruam tawg) los yog mos heev (nrhiav deformation). Cov ntoo tawv nrog qhov ntom ntawm 0.8-0.94 g / cm³, xws li Jujube lossis Jatoba (Brazilian Cherry), yog cov kev xaiv zoo heev; lawv muab kev tuav ruaj khov, tiv thaiv denting, thiab ua tau zoo nyob rau hauv ib puag ncig nrog kev hloov pauv ntawm qhov kub thiab txias.
Kov rau cov khoom siv hauv chav ua noj: Ua ntej ntoo uas muaj dej- tiv taus, tshav kub- tiv taus, thiab tsis muaj ntxhiab. Xyuas kom lub ntsej muag raug kaw nrog cov zaub mov- qib hardwax roj los tiv thaiv pwm kev loj hlob los yog leaching ntawm cov teeb meem tshwm sim los ntawm kev raug dej ntev.
High-kawg, sau tau- qib tuav: Tshaj li cov qauv kev ua tau zoo, ua qhov tseem ceeb ntawm cov ntoo zoo nrog cov qauv zoo thiab nplua nuj, xim sib sib zog nqus- xws li African Blackwood lossis Siamese Rosewood. Cov ntaub ntawv no coj mus rau ib qho lustrous, oily sheen tom qab polishing thiab txhim kho patina zoo nkauj los ntawm kev tuav ntau zaus.
